GUSTAV A. PETERSON, OF FLORENCE, MINNESOTA.

SETTING-GAG E FOR AXLES.

SPECIFICATION forming part of Letters Patent No. 640,804, dated January 9, 1900.

Application filed August 23,1899. Serial No. 728,203. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV A. PETERSON, a citizen of the United States, residing at Florence,in the county of Lyon and State of Minnesota, have invented certain new and useful Improvements in Setting- Gages for Axles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gages for setting all kinds of axles, rods, and shafts, but more particularly for setting vehicle-axles; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the gage. Fig. 2 is a plan view of the gage. Fig. 3 is a view of one end of the gage-bar. Fig. 4. is a view of its opposite end.

A is a bar, which is preferably tubular for lightness, and b is a forked contact-piece depending from one end of the bar. The middle part of the bar is preferably cranked upward to clear projections on the axle.

B is a handle secured to the middle part of the bar for convenience in lifting the gage.

O is a vertical stem which is journaled in hearings in the other-end portion of the bar A fromthe contact-piece b and is provided with a laterally-projecting pin 0 at its lower end.

D is a cross-bar pivoted on the pin 0 and provided at its ends with depending forked contact-pieces d.

E is a nut screwed on the pin 0, and e is a spring between the cross-bar and the nut, so that the resistance to movement of the crossbar upon its pin can be varied and adjusted.

F is a graduated index-plate secured to the bar A, and f is a pointer pivoted on a pin f, projecting from the bar A.

G is an arm secured to the stem 0 and operatively connected with the pointer. The arm G preferably carries a pin g, which ongages with an elongated hole g in one end portion of the pointer. The other end of the pointer comes over the index-plate.

H is a friction brake-block arranged inside the bar A at one end and bearing against the stem G. The friction-block is pressed against the stem by a spring h, and h is aplug which is screwed into the end of the bar A and which serves to regulate the pressure of the spring. The spring-pressed friction-block operates to prevent the stem 0 from moving too freely and holds the pointer steady.

In applying the gage to the end portions of a vehicle-axle the contact-piece b is placed on one end portion (or any portion) of the axle, and the contact-pieces d are placed on its other end portion. The cross-bar D turns on its pivot, so that the contact=pieces cl adapt themselves to any inclination of. the end portions of the axle in a vertical plane.

If the end portions of the axle are in line in a horizontal plane, the pointer remains opposite the zero-mark on the index-plate; but if the end portions are not in line in a horizontal plane the stem 0 is turned, so that the pointer is moved and indicates on the indexplate the extent and direction of the deviation of the end portions of the axle from the true alinement. The arm is long, and the slotted end of the pointer is short, so that a small movement of the stem produces a large movement of the free end of the pointer.

The axle is set in any approved manner until the gage shows that its end portions have the desired alinement.

What I claim is-- 1. In a setting-gage, the combination, with a tubular bar provided with a contact-piece at one end, of contact mechanism provided with a stem which is journaled in the other end portion of the said bar, a frictional brake inclosed within the said bar, and an indicating device connected to the said stem, substantially as set forth.

2. In a setting-gage, the combination, with a bar provided with a contact-piece at one end, of a stem journaled in the other end portion of the said bar and provided with means for indicating its movements, a cross-bar pivoted to the said stem, and a tension device for resisting the movements of the said cross bar, substantially as set forth.

3. In a setting-gage, the combination, with a tubular bar provided with a contact-piece at one end, of contact mechanism provided In testimony whereof I affix my signature with a stem which is journaled in the ether in presence of two witnesses.

end portion of the said bar, a swin -pressed 1 V 1 1 Z friction-block arranged inside the bar and GUSTAV PETEREON' 5 bearing against the said stem, and a screw- XVitnesses:
